F-阈值是特征零中的乘数理想的跳跃系数的特征p模拟。本文给出了正则F-有限环R$中理想的F-阈值的另一种描述。这使我们能够解决两个悬而未决的问题提出[Mustata，Takagi，Watanabe：F-阈值和Bernstein-Sato多项式]，即我们表明，F-阈值是合理的和离散的。
The F-thresholds are characteristic p analogs of the jumping coefficients for multiplier ideals in characteristic zero. In this article we give an alternative description of the F-thresholds of an ideal in a regular and F--finite ring $R$. This enables us to settle two open questions posed in [Mustata, Takagi, Watanabe: F-thresholds and Bernstein-Sato polynomials], namely we show that the F-thresholds are rational and discrete.
